I PROCESS FOR THE PRODUCTION OF FOOD PRODUCTS Filed Feb. 3, 1928 J11 ucufoz a51 QZMZ KW Patented Apr. 28, 1931 outrun STATES PATENT OFFICE BRUCE NELSON PULVER, OF AKRON, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, 'TO

ALL IN ONE CORPORATION OF AMERICA, A CORPORATION or NEVADA PROCESS FOR THE PRODUCTION OF FOOD PRODUCTS Application filed February 3, 1928. Serial No. 251 ,518.

This invention relates to a new and im-- proved process for the production of food products and particularly to a new and improved process for providing an edible envelope or casing, such as the sandwich biscuit shown in my pending application, filed November 16, 1927, Serial No. 233,631.

The object of this invention is to provide an expeditious and quick method of making an edible envelope or casing suitable for receiving "sandwich filling, such as a sausage, frankfurter, or Wiener-Wurst, and practically enclosing the same.

With these ob'ects in view and with the intention of securing other advantages which will hereinafter appear, my invention consists in the process hereinafter described in the specification and particularly set forth in the claims.

Referring to the accompanying drawings, Fig. 1 illustrates an edible product such asa mass of baked dough commonly termed a biscuit together with one type of a device for carrying out my process. Fig. 2 is a view showingthe biscuit in cross section and the device in a modified form inserted within the biscuit.

An implement which I may use in carrying out my process is shown in Fig. 1. This im-,

plement which I term a piercing and compacting device may comprise'a body portion 5 providedwith a pointedend portio R. The body portion 5 is preferably mounted on a handle portion area of the piercing and compacting device will generally be a,little greater than the cross sectional area of the desired cavity or chamber in the envelope or casing which is to be produced.

In carrying out my process I take a product, shown at B, resulting from baking a quantitv. of dough so that a more or less definite crust is formed on the exterior of the product while the interior thereof is light and porous. I then take the piercing and compacting device and insert the pointed end thereof at one end of the said baked product and cause the device to move inwardly, centrally, and longitudinally of said product to a short distance of the opposite end of 7. The cross sectional said product. The insertion of said device into said product will displace the material at the center of said product and force it outwardly in all directions and will compact it to a certain extent in the immediate vicinity of said device. The device may also be given a slight twisting or rotary movement as it is inserted into and longitudinally of said product.

The device is permitted to remain within the product for the length of time necessary to When the device is withdrawn from the product a cavity or chamber B will have been formed within said product suitable for the reception of any sandwich filling which it may be desired to use.

I have found that if the piercing and compacting device be heated it will more easily pierce and pass into said product, and also that if suflicient heat be supplied to said de-I vice the wall of the cavity or chamber formed in the product will be seared or toasted. This searing or toasting of the wall of the cavity or chamber not only gives a more definite set to the wall of the chamber but also greatly enhances the taste of the envelope or casing produced.

In Fig. 2 I have shown a suitable device which may be used in carrying out my process when it is desired-to sear or toast the wall of the cavity or chamber. The device may comprise a tubular member 15 which is suitably mounted upon a handle 16 preferably formed ofan insulating material. Within the tubular member 15 is a suitable electrical heating unit 17 which may be connected with a source of electricity by means of wires 18 connected to said heating unit and extending down through the tubular member 15 and the handle 16. The forward end of the tubular member is closed by a pointed plug 19.

I do not wish to limit myself to any particular type or form of implement for'use in carrying out my process as various devices may be employed and difierent methods for heating the same may be employed when the heating of the device is desirable.

What I claim is: p

1. A new and improved process for preparpermit the material of the product to set. 1

ing an edible which consists in initially piercing the solid body of a preformedv baked dough edible with a heated element, continuing the piercing displacement of said heated element within the body of said edible to form a cavity therein, and retaining said heated element Within said cavity for a period suflicient to toast the wall thereof.

2. A new and improved process for, preparing an edible which consists in initially piercing the solid body of a preformed baked dough edible with a heated element, continuing the piercing displacement of said heated 'element within the body of said edible to form a substantially cylindrical cavity there-' in. and retaining said heated element within said cavity for a period suflicient to toast the wall thereof. 3. A new and improved process for preparing an edible which consists in initially, piercing the solid body of a preformed baked dough edible with a pointed heated element, continuing the piercing displacement of said heated element within the body of said edible 26 to form a cylindrically elongated end enclosed cavity therein and retaining said heated element within said cavity for a period sufiicient to toast the wall thereof.

4. A new and improved process for pre- 30' paring an edible which consists in initially piercing the solid body of a preformed baked dough edible with a pointed heated element, continuing the piercing displacement of said heated element within the body of said edible 3 5 to form a cylindrically elongated end enclosed cavity therein and retaining said heated element within said cavity for a period sufficient to impart a retaining shape to said cavity. 40 In testimony whereof I affix my signature.
